Seems like a poor choice for $1400ish.

AMD = bad , Intel (C2D) = good
4GB of memory is overkill, and you won't be able to use all of it unless you specifically get vista 64 bit (or XP 64 bit).

Does the video card have 2 ports allowing you to use 2 monitors if you decide to do that later?

The price difference for a 320GB HD and 500GB HD is $80 on dell's site, but a 320GB HD by itself costs $80 and a 500 GB drive is $10-20 more. You're paying $80 for an extra 180GB but you use the computer for nothing except poker and standard web browsing. Seems cost inefficient to get the larger drive because 320GB is already a ton for what you're doing.
